1. Field of the Invention
The present invention relates to a diet device and more specifically to a placemat which records all of an individual's intake of substances with information concerning the substances such as calories and a method to control said intake.
2. Prior Art
Many people are presently struggling with various diet restrictions and diet requirements. Intake of foods, drugs, alcohol and the like is very easy to forget about and even if the substance is recalled the amount consumed is unknown. There is also too strong an emphasis on the part of the participant and the diet method on the particular forbidden substance. Writing things down is too prone to cheating. Merely counting by any means leads to cheating in the amounts and most totalyzing means are cumbersome or subject to procrastination. The average American eats out at least three times a week and it can be used as an excuse to get off the diet. When the diet requires an unpleasant-looking cumbersome kitchen device its easy to see why its left at home. Simple kitchen scales are therefore not used commonly for this. Besides the above disadvantages there has been no easy-to-use way to passively record intake of food and the like. Instead of requiring any special behavior its useful to have a method which uses our present behavior--i.e. eating from plates, bowls etc, which are on a surface. A placemat which is portable is an ideal way to influence a control method on our eating, drinking etc. behavior. Special behavioral techniques using positive reenforcement for the increase in allowable food can be applied appropriately when a truly complete measurement method is being employed. Disorders such as Anorexia Nervosa may well respond better to methods of mere recording for the user without the problem of overemphasis any written account has.
People under nursing care often do not eat properly and a more automated method may better influence better eating for patients. There is no prior art found which passively records and/or controls intake of food and other substances.
The principal object of the present invention is to provide a novel device using a unique method to assess the intake of all nutritive substances in an unobtrusive, utilitarian and easy-to-use way.
Another object is to utilize this method incorporating this device to provide a means for a method of behavioral feedback using various chosen factors to assist and provide a means for an individual's weight loss, weight gain, or fulfillment of special diet restrictions.
A further object of the present invention is to serve as a useful tool for health professionals to assess nutritive intake and to provide a means to diagnose and treat various health disorders.
The foregoing objects and others that are apparent are achieved through the use of a weight control placemat. The user of this method of control decides that everything which is consumed must be placed on the placemat. Once this decision is made it can then passively record all intake. It is a well known theory that control can better be attained when good measurement is being made. Feedback is also important and with this method the desired factors such as but not limited to amounts of food groups, calories, time, behavioral information, emotional well-being, health information and the like conducive to control can be chosen as feedback information to the individual or supressed and instead only used to inform a health professional.
The preferred embodiment has a surface divided into food groups. Each food is placed on the placemat in sequence and zeroed between dishes. The amount of each food group is then stored in each register. Additional information regarding the food such as calories per gram can be recorded as total amounts in a register. Leftovers are subtracted from these totals providing a sound measurement. Printing means are optional to provide a written record. Otherwise selected totals are read periodically (i.e. daily) and noted.
The features and advantages of the present invention will become apparent from the following detailed description of the invention when read with the accompanying drawings.
FIG. 1 is the most preferred embodiment of the weight control placemat of the present invention.
FIG. 2 is a flowchart of the use of this embodiment.
FIG. 3 is an illustration of the use of a second embodiment which appears identical to FIG. 1 but the category areas are each weighed seperately using individual scales.
FIG. 4 is an alternate embodiment showing a mechanical way to design the weight control placemat of the present invention.
Referring specifically to FIG. 1, there is illustrated the most preferred embodiment of the weight control placemat. This invention includes a placemat 1 of sufficient size to hold all contents of a meal. It is device composed of a measuring method using an electronic, strain gauge scale which transmits an electronic signal. This is then recorded in unit 2 an electronic device along with any other factors. The unit is turned on and zeroed through 3 and category 8 is entered using the keys 5. The keys 9 allow entering of the weight data along with optional information which may include but not limited to calories, fat, salt, cholesteral and the like. Information counting number of glasses of water, beverage, or drug as in 10 is also entered. Condiments, 4, are entered also. Additional information such as but not limited to time, exercise information, emotional well-being and the like can also be entered through 5 and keys 9. A display 6 and an optional printer 7 are available for reading or recording.
Referring now to FIG. 2 we can see the flow of information and operation of this invention. Food F is placed on the placemat. Signal S is transmitted and additional factors C(Calories per gram) and O (Optional factors such as fats, cholesterol, salt, sugar and the like) are sent to register Mn (totalyzing amount) and Mno (amount multiplied by O optional factors). In Step 2 of FIG. 2 the leftovers including plates, utensils etc. L are measured and subtracted from the previous total P.T. each time a dish is removed. It is then entered in the appropriate register including or not including the optional information Mno or Mn.
An alternate embodiment of this design is FIG. 3. Its appearance is the same as FIG. 1 but the categories operate seperately. Instead of one weighing mechanism individual mechanisms which are electronic scales, are used for each category. In Step 1 the first item Fl is measured along with any factors C and O and placed in register Ml. This can be done by entering or automatically. Additional items are measured individually Fn and the amounts placed in registers Mn. In Step 2 the leftovers for Ll and Ln are subtracted from the amounts in memory Ml and Mn.
Referring to FIG. 4 there is another preferred embodiment which uses an alternate method of recording and control. It also is a weight control placemat comprising two panels 1 and 2 and opposite weighing mechanisms 3 supporting Panel 2. Lengths of paper 4 placed on 3 are marked off using a pen or maker or cut using a stylus or scissors or torn with the fingers according to the travel of the pointer 7 on 3. This travel represents the addition of each dish of food. Upon completion of the meal the paper can be decreased in size by making, cutting, or tearing according to the amount of leftovers and the weight of containers. Disks 5 are used to measure the amount of condiments, beverages if desired, pills etc. A record for each meal is easily placed in food diary 6 using the cut, torn, or marked tapes 4 and disks 5. The panel 1 can also be used as a visual method which graphically shows the length of tape corresponding to the amount of each food or food group to continually assess the amount of consumption of food and the like. Additional information such as time of day, emotional well being and health factors can either be written or coded as a sticker and placed on a placemat and/or kept in the diary to be used for the use of the user or healthcare professional to assess eating habits.
While preferred embodiments of the present invention have been shown and described herein, it will be obvious that such embodiments are provided by way of example only. Numerous variations, changes and substitutions will occur to those skilled in the art without departing from the invention herein. Accordingly, it is intended that the invention be limited only by the spirit and scope of the appended claims.
